None of this has been necessary for years, since\nnetpoll invokes NAPI directly."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: eth: sungem: elimine .ndo_poll_controller para evitar interbloqueos Erhard informa advertencias de netpoll desde sungem: netpoll_send_skb_on_dev(): eth0 habilit\u00f3 interrupciones en la encuesta (gem_start_xmit+0x0/0x398) ADVERTENCIA: CPU: 1 PID: 1 en net/core/netpoll.c:370 netpoll_send_skb+0x1fc/0x20c gem_poll_controller() desactiva las interrupciones, que pueden dormir. No podemos dormir en netpoll, tiene las interrupciones desactivadas por completo. Curiosamente, gem_poll_controller() ni siquiera sondea las finalizaciones y, en cambio, act\u00faa como si se hubiera disparado una interrupci\u00f3n, por lo que simplemente programa NAPI y sale. Nada de esto ha sido necesario durante a\u00f1os, ya que netpoll invoca directamente a NAPI."
